Etymology: Brachiopsilus: Name from Latin 'brachium' (arm) and Greek 'psilos' (bare or smooth), referring to the smooth surfaces of their body and arm-like pectoral fins.; ziebelli: Named in honour of Alan Ziebell, a professional diver, who hand collected some of the first
specimens near the Actaeon Islands (D’Entrecasteaux Channel) when fishing for abalone. These specimens were initially displayed in a marine aquarium at his home a.

Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 18 - 20; Anal spines: 9 - 10. Member of the genus Brachiopsilus with a combination of the following characters: esca
small, 19–32% of illicium length; illicium thick, fleshy, length 18–24% SL, 2.4–3.0 times in head length, 1.2–1.4 times in length of second dorsal-fin spine; apex of esca situated well posterior of hind margin of eye when illicium adpressed; esca slightly wider than illicial stem, covered with dense, short papillae; head bulbous; eye small (horizontal diameter 5–6% SL); mouth broad; lips very fleshy with vertical folds; body and fins entirely naked in adults (except for scales associated with pores of the acoustico-lateralis system); 4 sensory pores
above eye; short first dorsal-fin base (length 21–25% SL); second dorsal-fin rays 16–18, length of fin base 63–70% SL; length of second dorsal-fin spine 0.8–1.2 times length of longest ray of second dorsal fin; 9–10 anal-fin rays, length of anal-fin base 34–38% SL; 9 pectoral-fin rays; short caudal peduncle (length 2–5% SL); caudal fin small, its length barely longer than fin rays of pectoral fin, length 2.7–3.4 times caudal peduncle depth; body whitish with fine, greyish purple peppering; fins vivid yellow (Ref. 82446).
